ABSTRACT

An apparatus and method is presented for network video management and recording of video signals and video analytics generated by a network of IP-enabled cameras. A set of IP cameras are connected in a LAN to a network video recorder further connected by LAN or WAN to a set of client stations. The client station operates a hybrid program including a web-browser and a native application operating on a computer. The network video recorder operates a media recorder to store video streams from the IP cameras into a media database and further operates a relational database for storing camera configuration data, device drivers, event information and alarms. The network video recorder includes a zero configuration networking discovery service for automatically detecting and downloading default configurations to the cameras. Client stations can stream video directly from IP cameras, receive recorded video streams and query the relational database for cameras and events.

FIELD OF THE INVENTION

This disclosure relates to the managing and recording of video and local events from a set of remote security devices over an internet protocol based network.

BACKGROUND OF THE INVENTION

Video security systems require large computer networks in order to respond to modern security requirements. Typically, hundreds of cameras and peripheral devices require installation and maintenance to produce satisfactory results. System maintenance requires substantial professional time to carry out. Further, system expansion and upgrade require considerable configuration and professional attention, for example, providing power to each device, connecting a data link from each device to local monitoring equipment, providing a communications link between a central security site and the local monitoring equipment within each building on a campus, assigning locations and ports to each device, and the manipulation and storage of video and other data streaming from the devices. All are currently labor intensive tasks which are prone to error and repetition.

Modern security networks benefit from the technology of Ethernet networks and IP routing. But, as the size of the network grows, manageability of the system often becomes an overwhelming task. For example, system maintenance requires an IT team to service the network, assign routers to subnetworks of security devices, set up the routers to route signals properly using combinations of DHCP and static routing assignments, and track of routing tables as the security network grows.

In some cases, large security systems have multiple campuses monitored at a single security site, necessitating use of the Internet. However, use of the Internet adds the issues of management of firewalls and other security considerations. The use of Ethernet, IP routing and the interest in security systems raises the need for automatic configuration.

Upgrade of a security system presents additional challenges. For example, no generally accepted standard for IP video systems exists. Each IP security camera and device typically requires a proprietary driver used for configuration and monitoring. Proprietary drivers require installation and constant update. The installation and upgrade process is therefore time consuming and unwieldy. The result is a need for a “plug and play” format for IP security devices to eliminate upgrade issues.

In many security systems, digital video recorders are employed to store video data from multiple cameras. Video data is typically stored in a database. Such databases soon become extremely large and unwieldy. Monitoring and maintenance of the database and elimination of unwanted data presents an additional challenge to the maintenance and upgrade of security systems.

Modern cameras used in security systems can perform many tasks internally. Examples are managing and controlling pan, tilt and zoom (PTZ) control, sensing I/O events, sensing audio events, providing a web interface on the camera for log in, controlling the camera parameters and event handling, and video analytics, such as motion detection. Examples are discussed in “AXIS and Intelligent Video (IV)” from Axis Communications, published 2009, incorporated by reference. However, to accomplish these tasks, configuration of the cameras must be done at installation. Further, greater capability of cameras results in more complex and time consuming installations.

U.S. Pat. No. 7,543,327 to Kaplinsky attempts to answer some of the issues in facing video security systems. For example, this patent discloses a video system including one or more high resolution network video cameras creating full field reduced resolution views and full resolution subwindow views. The video cameras are capable of simultaneously generating a full field of view reduced-resolution of an image and a full-resolution sub-window of the image. The computer is configured to receive images from the video cameras via a computer network and display the images on the monitor in which a full field view of the image and a sub-window of the image are displayed on the monitor simultaneously. Kaplinsky does not disclose or suggest “plug and play” camera detection or multiple automatic video services.

U.S. Patent Publication No. US2007/0226616 to Gagvani, et al, discloses a security system including a network with a plurality of sensors having network addresses, each generating sensing data. Software on the computer network communicates with the sensors and manages a display showing sensors in the system. A managing component communicates with the sensors by access through the associated network address on the network, and processes sensor information received from the sensors. The managing component has a display with an interface screen showing to a user all the sensors in the security system, and an input device through which the user can enter interactive instructions to the managing component. Gagvani et al does not disclose automatic detection of cameras or automatic configuration.

U.S. Patent Publication No. US2003/0117500 to Lin discloses a network video recording system which includes a video server controlling a video camera. A monitoring device connected to the video server which monitors the video image. The system includes at least one video server, at least one network storage device, and a monitoring device. The video server controls a video camera in order to obtain video image data by video recording, and sends the data via a network. The network storage device is connected to the video server with the network to receive the video image data sent by the same via the network and stores the video image data. The monitoring device is connected to the video server and the network storage device with the network for monitoring the video image data sent by the video server. The monitoring device may be used as a monitoring interface, or control the network storage device to send the video image data stored to the monitoring device for required inspection. However, Lin does not disclose automatic configuration or detection of video devices.

U.S. Patent Publication No. US2008/0199155 to Hagens, et al, discloses a server-based software application which collects video images from cameras and sends them to a data collection device connected to a data center which stores the video images and transmits them on demand. Digital video recorders (DVRs) collect media (such as video with or without audio) and record it to a local disk. DVRs are located at sites where they are attached to cameras, microphones and point-of-sale (POS), or other data collection devices. A server-based application makes the data collected accessible to users. Viewers can then connect to the DVR and its corresponding media collection devices (such as cameras, microphones and POS devices) and control collection and use of media information directly. Hagens et al does not disclose “plug and play” camera applications or processing of event-driven camera actions.

U.S. Patent 7,855,729 to Onodera discloses a video recording system which includes multiple cameras and video recorders. The monitor cameras are assigned to the video recorders in a manner such that each of the video recorders corresponds to at least one assigned monitor camera. Each of the monitor cameras sends its video signal to the assigned one of the video recorders. The video recorders record the video signals sent from the cameras. A failure detection system operates to locate failing of the video recorders. When detected, the assignment of the cameras to the video recorders changes so that the camera assigned to the failed video recorder is assigned to another video recorder. However, Onodera does not disclose “plug and play” camera detection, event-driven activities, or any monitoring of a video database.

Network switches often provide a mechanism to bind an Ethernet port to a client device with a particular media access control (MAC) address. This enhances the security of the system by limiting communications over that port to a single designated device. However, presently this mechanism is often not used because it greatly increases the administrative workload of setting up the system. In the prior art, each client device must be investigated and its MAC address determined. This can be done physically by inspecting the label on the device, or programmatically by establishing an Ethernet connection to the device and then requesting its MAC address. Common consumer software utilities do not conveniently generate a list of those addresses and so the task of gathering this information is arduous. Once the list of MAC addresses is gathered, it must be manually entered one at a time into the Ethernet network switch device in order for the binding to occur. Because of the manual nature of this task, proper operation of the client device must then be tested.

SUMMARY

Disclosed is a network video recording system that automatically powers, detects, accepts, identifies, configures and records data from a series of video cameras connected to a computer network. The system provides an automated “plug and play” feature that automatically installs and configures video cameras. Manual installation of software drivers or networks of Ethernet switches is not required. The system responds to various network and camera conditions greatly reducing the amount of installation and maintenance time required to operate the system.

Accordingly, the system is comprised of a set of network cameras, a network video recorder, a PC workstation client running a client controller software enabled as an IP client station. The set of network cameras is connected to the network video recorder without the addition of an external Ethernet switch. The IP client station is connected to the network video recorder through an uplink port that may be reached via a standard TCP/IP network. The network video recorder is connected to the IP client station either locally over a power over Ethernet (PoE) connection or remotely through a network router via Wi-Fi. The system is capable of connecting multiple video recorders to a local IP client station or to remote IP client station.

The network video recorder is comprised of a microprocessor, memory, BIOS flash memory, Solid State Disk Drive, SATA Hard Disk Drive and multiple Power over Ethernet (PoE) (IEEE 802.3af, 802.3at) enabled network interface ports. The number of network interface ports is preferably in configurations of 4, 8, 16 or 24 ports per recorder, the number of ports being limited only by the processing capability of the microprocessor and throughput of the memory, communications components, and Solid State Disk Drive.

In an alternate embodiment, the network video recorder may be adapted to embed a layer-2, Ethernet switch which then communicates with and coordinates signals to the network interface ports as wired RJ45 ports.

The network video recorder comprises Ethernet ports capable of accepting and recognizing cameras. The video recorder is comprised of a processor module, a heatsink and a carrier board. The processor module includes a microprocessor connected to memory. The processor module further comprises a system controller connected to a BIOS Flash. The carrier board includes at least one of group of multiple 10/100/1000 Base-T RJ-45 ports for the PoE connection, and multiple 10/100 M Base-T RJ-45 ports. The carrier board further includes one 10/10/1000 M RJ-45 port, one VGA (DB15) video monitor port, one E-SATA port and three USB 2.0 ports. Removable mass storage is operatively connected to the E-SATA port. Additionally, the carrier board includes an additional SATA port, an E-USB flash connector, a compact flash card socket, a system fan connector, and a power connector for a hard disk drive.

The network video recorder includes a control software, which when executed by the processor board, implements an automated “plug and play” mechanism, real-time video recording, video searches, video playback through a graphical user interface (GUI) and live video streaming from security devices.

The control software and operating system is stored on the solid state disk drive.

The video recorder supports all network cameras compliant with the ONVIF (Open Network Video Interface Forum) interoperability standard. The video recorder implements an automated “plug and play” capability for cameras connected through the PoE RJ-45 ports. Upon connection, all cameras are automatically powered, assigned an IP address, configured to a default video quality profile and recorded to hard-drive.

The automated “plug and play” capability requires no external network Ethernet switch or external power source. The automated “plug and play” capability is completely unattended, requiring no manual software, recorder or camera configuration steps or other user interaction.

The automated “plug and play” capability is implemented through control software instructions running on the processor module. The software provides an IP network discovery service for IP address assignment to the attached cameras. The software provides a library of software drivers to communicate and to provide configuration and video streaming instructions to the cameras attached to the RJ-45 ports. The software provides specific command and control instructions to the cameras for automated camera configuration. The automated camera configuration includes setting the features of video quality, video compression format, video frame-rate, time of day, motion detection configuration, motion sensitivity, and external I/O switching. In one embodiment, the IP network discovery service requests and downloads the library of camera software drivers from an internet server and configures the cameras using the software drivers.

The control software implements a video recording service to capture video streams from the RJ-45 ports. Video streams are stored on disk drives attached through an internal SATA connection, external SATA (eSATA) port or network attached storage (NAS) devices.

The control software implements a video streaming service to stream live and recorded video over RTP/TCP/IP to the IP client station via IP client controller software.

The control software supports an IP client controller software download, set up and initialization. The IP client controller software supports an automated client update service. Each time the client software is started from a remote PC, it will automatically check a web-based service to search, download and install software updates.

The control software in combination with the client software supports live viewing, PTZ control, camera tours and pre-defined camera views.

In use, the network video recorder receives instructions from the IP client station related to preferences of the user with respect to configuration of the network cameras. For example, camera choices, delay times, and PTZ parameters are selected through a graphic user interface produced by the client software operating on IP client station.

An IP network discovery service running on the network video recorder searches the network for available cameras connected at the RJ45 ports. Each Ethernet port controller associated to each RJ45 port reports specific connectivity data on a connected camera or other network security device including a fixed Mac-address which is stored in a SQL database. The network video recorder then configures each of the cameras, according to directions from the processor module, using camera specific data stored in the persistent memory (compact flash memory or mass storage device).

Once configured, the media recorder sets up streaming protocol channels to the cameras, and the event manager receives event and alarm data from the cameras including video streams and event transactions, according to instructions from the scheduler. Subsequently, video streams are stored in the media database and event/alarm transactions are stored in the SQL database via the mass storage device on the SATA port.

In FIG. 9, carrier board 61 includes four 10/100/1000 Base-T RJ45 ports for the set of Ethernet ports 66 controlled by a set of fast Ethernet controllers 76 which are connected to and driven by the system controller 72. PoE source 77 provides power to enable PoE to the set of Ethernet ports 66. Carrier board 61 includes an additional 10/10/1000M RJ-45 uplink port 67 driven directly by system controller 72. Wireless communications is enabled to carrier board 61 by a wireless mini PCIe card plugged into a mini-PCIe slot 80 provided on carrier board 61 and driven by the PCI express interface of system controller 72. A video port monitor port 68 is driven by microprocessor 71. SATA and E-SATA ports 79 driven by system controller 72 are further connected to internal removable mass storage 75 which is preferably a 2.5 or 3.5 inch HDD or SSD. USB ports 69 provide USB 2.0 signals from the system controller to the back panel via a 2×1 stack USB connector and to an internal E-USB flash port. Additionally, the carrier board includes one compact flash card socket 78 suitable for connecting compact flash memory to system controller 72, and power connectors for the 2.5 inch HDD and a cooling fan (not shown).

In use, the processor module of the network video recorder instantiates and executes a number of software modules as instructions stored in compact flash memory or in the external mass storage. FIG. 10 is a block diagram showing the function of the network video recorder system and indicating data flow and communication between the software modules involved.

In FIG. 10, the network video recorder system includes the network video recorder 1 in communications with an IP client station 2, at least one IP camera 3, and update server 4. Network video recorder 1 communicates with IP client station 2 and update server 4 through a LAN or through the internet 8 as required. IP client station 2 can communicate to IP camera 3 on a LAN using the network video recorder to enable RTSP streaming directly from IP camera 3 to IP client station 2 on LAN based connection 5. IP client station 2 can communicate to IP camera 3 on a WAN using a proxy server 6 to set up an internet based connection 7 through internet 8. IP client station 2 is in communication with update server 4 via the internet to receive automatic updates of client software and network security device drivers for the network video recorder. Network video recorder 1 is in communication with update server 4 via the internet to request and receive network security device drivers for the network video recorder and for IP camera 3.

IP camera 3 is configured with video analytics and IP communication protocol according to the open network video interface forum (ONVIF) standard or proprietary standards from supported manufacturers and is preferably connected to network video recorder 1 with a wired PoE link.

Network video recorder 1 includes a number of automated services instantiated and executed by the processor module to operate based on the occurrence of security device events, a pre-determined schedule, and network-based events. A control software module coordinates the automated services and communications there between.

Network video recorder 1 includes an IP network discovery service 12, a program that when executed by the processor module, functions to sense the presence of IP camera 3 and all other IP-enabled security devices attached via Ethernet to the network video recorder. IP network discovery service 12 enables automatic discovery of computers, devices, and services on IP networks using industry standard IP protocols to allow devices to automatically discover each other without the need to enter IP addresses or configure DNS servers. Specifically, IP network discovery service 12 enables automatic IP address assignment without an external DHCP server, name to address translation without a DNS server, and service discovery without a directory server. A suitable plug-in module for IP network discovery service 12 implements zero configuration networking. An example of such an implementation is the “Bonjour Open” protocol from Apple, Inc. which has been submitted to the IETF as part of the ongoing standards-creation process.

Network video recorder 1 includes HTTP server 16 operated by the processor module for serving http web pages to IP client station 2 and enabled to allow IP client station 2 to download client software and to configure the services of network video recorder 1. HTTP server 16 can serve web pages directly through a LAN or over a WAN via internet 8. Network video recorder 1 includes two databases: a media database 20 and a SQL database 21 which are electronically stored on the mass storage device or the compact flash drive. Media database 20 is preferably a flat file database for storing and accessing recorded video files. SQL database 21 is preferably a relational database containing data pertaining to IP security devices, events, and metadata associated to recorded video files. Typical data stored in SQL database 21 includes security device data comprising MAC address, name, manufacturer, IP address, model, default configuration, device drivers and events associated to the security device.

IP network discovery service 12 is programmed to automatically configure IP camera 3 once it is detected in the network, from a default configuration stored in SQL database 21. The default configuration for an IP camera device includes time stamp synchronization to network video recorder 1, choice of compression algorithm (e.g. H.264), image quality, image size, frame rate, PTZ parameters, enabling/disabling of motion detection, and enabling/disabling event detection based on I/O contact closure events, motion detection events and audio events. IP network discovery service is further programmed to store IP addresses and MAC addresses of IP-enabled security devices including IP camera 3 in SQL database 21 upon discovery.

IP camera 3 is also connected to I/O contact closure 50. I/O contact closure is an analog port which can be accessed to indicate contacts of magnetic closures (such as door contacts), fire alarms, manual (panic) buttons or other manual inputs such as card key reader authorization, or security tour confirmation checkpoints. Data related to the event including data characterizing the type of event and reaction to be taken is stored in the SQL database upon camera discovery and setup.

Network video recorder includes a database groomer 14 which is a service that is instantiated and executed by the processor module. Database groomer 14 is programmed to become active periodically in order to perform “clean-up” functions on media database 20 and SQL database 21. The clean-up functions include eliminating old events from SQL database 21 and old recorded video files from media database 20. The clean-up is preferably performed on a first-in-first-out basis. IP client station 2 is capable of being configured to periodically or manually download recorded video files for archival storage for example on a local hard drive, R/W DVD disc drive, and USB flash drive.

Database groomer 14 is further configured to create XML metadata files for events and for recorded video files, and to attach those XML metadata files to the events and recorded video files in SQL database 21 and media database 20, respectively.

Network video recorder 1 includes event manager 15. Event manager 15 monitors events recorded from each IP camera and coordinates actions of the system to correspond to the event. For example, when a camera detects motion, an event notification is sent via TCP/IP to the Event Manager. In another example, when a camera detects a tampering event, such as blocking the view of the camera, smashing the camera, or breaking the lens of the camera off, an event notification is sent via TCP/IP to the Event Manager. The Event Manager processes the event according to configurable user instructions. Motion events trigger video recording by default.

A table showing a list of events and corresponding actions appears below:

TABLE 1 Event Action I/O contact closure Video recording, Alarm notification on a user interface, alarm notification via messaging (SMS, email, smart phone push) Motion detection Video recording, Alarm notification on a user interface, alarm notification via messaging (SMS, email, smart phone push) Audio detection Video recording, Alarm notification on a user interface, alarm notification via messaging (SMS, email, smart phone push) Video Loss Reset camera via TCP/IP command, reboot camera by toggling PoE power to camera Tamper detection Video recording, still image capture, Alarm notification on a user interface, alarm notification via messaging (SMS, email, smart phone push) Event manager 15 also functions to capture events as they are logged by IP camera 3 and to store events in SQL database 21, and schedule recorded video files with scheduler 18 based on the occurrence of an event. Scheduler 18 functions to receive events from event manager, time stamp the event and initiate media recording based on interactions with event manager 15. Scheduler 18 is further programmed to periodically perform actions, such as video recordings from specific sets of cameras at pre-determined times. Scheduler 18 further functions to schedule video session recordings based on an event priority level, available throughput and available storage. Scheduler 18 further functions to look up the IP address of an IP security device and forward the IP address to media recorder 10.

Attached to event manager 15 is alarm delivery service 13. Alarm delivery service 13 functions to create alarm events based on event thresholds, associate alarms to actors, and to deliver a communication to an actor upon an associated alarm event. Actors can be services within network video recorder 1. For example, a motion detection event triggers an alarm for IP camera 3 and alarm delivery service 13 functions to send a message to scheduler 18 to initiate a media recording session. Another example is an I/O trigger event. Alarm delivery service 13 may also transmit a message to a person via email, text, paging, or phone call. Alarm delivery service 13 also functions to log all alarms to SQL database 21.

Network video recorder 1 includes media recorder 10 which is a service program instantiated and executed by the processor module to record video files. Media recorder 10 functions to receive an IP address from scheduler 18 of a selected IP security device, set up an RTSP streaming media session (audio or video) with the selected IP security device, and record the video session after appropriate decoding into media database 20. A preferred file format for storing recorded video files in media database 20 is the .asf format from Microsoft.

Media recorder 10 further functions in coordination with database groomer 14 to organize recorded video session files on media database 20, managing disk space and storage blocks to accomplish an efficient storage and subsequent file streaming. Media recorder 10 pre-allocates block space for each video file. Pre-allocation of block space avoids fragmentation of the disk drive and eventual slowing due to re-write access. Examples of pre-allocated block space include one gigabyte per video file before FIFO deletion.

Media recorder 10 serves recorded video files as streaming video files over the LAN or WAN to IP client station 2 and to the video monitor port of network video recorder 1. In selecting recorded video files for streaming, media recorder 10 functions to respond to search queries received from IP client station. The search queries are performed on events in the XML metadata files in SQL database and on an index of recorded video files stored on the SATA drive. The result of a search query is a segment of recorded video with a defined start and end-time.

In one embodiment, IP client station 2 operates a hybrid program consisting of a web browser to communicate with the HTTP server and a locally executable program to communicate directly with media recorder 10, SQL database 21 and IP security devices.

For example, IP client station 2 functions in coordination with SQL database 21 to obtain the IP address for IP camera 3 and initiate a streaming video session (or streaming audio session) from IP camera 3 to IP client station 2. If the IP address is on the local LAN connecting IP client station 2 to network video recorder, then the resultant streaming session is set up on LAN-based connection 5. If the IP address is not on the local LAN, then IP client station 2 requests a streaming session on WAN-based connection 7 via proxy server 6. The streaming session is typically an RSTP session set up according to an API interface on the IP camera.

IP client station 2 is further programmed to query SQL database 21 and receive responses describing events and alarms as stored in association with IP camera 3.

It is to be understood that the hybrid program is electronically stored within the hardware of IP client station 2 as the downloaded client software and is instantiated and executed by a processor within the IP client station 2. The network video recorder is also programmed to execute the hybrid program, using the network video recorder's VGA output and USB ports for keyboard and mouse control.

FIG. 11 shows a functional block diagram of another preferred embodiment of the network video system 1 wherein network video recorder 1 operates with security devices that are not IP enabled. FIG. 11 is especially applicable to upgrading an existing campus having legacy security equipment such as set of analog cameras 101, a set of POS devices 102 or a set of I/O contacts (alarm contacts) 106.

In FIG. 11, network video recorder 1 includes the functions as previously described for FIG. 10. An IP client station 2 interacts with network video recorder 1 via a LAN connection or via internet 8.

Set of analog cameras 101 is connected to an encoder box 103 which is further connected by Ethernet LAN to network video recorder 1, the encoder box functioning to encode analog video signals into an encoded format such as H.264. Encoder box 103 is discoverable by IP network discovery 12. Media recorder 10 functions to select at least one camera from the set of analog cameras through communications with encoder box 103 and stream video from encoder box 103 to recorded video files stored in media database 20. Media recorder 10 also functions to stream video directly from encoder box 103 to the video display monitor of the network video recorder. IP client station 2 functions to stream video directly from encoder box 103 for display.

For point of sale (POS) applications, set of POS devices 102 are connected to an Ethernet interface 104 which is further connected by Ethernet LAN to network video recorder 1, the Ethernet interface functioning to translate physical signals from each POS device into an IP packet stream, the physical signals representing transactions such as the logging in/out of a teller or a sales clerk. For example, a first POS device is connected by a RS232 serial link 105 to Ethernet interface 104 programmed to translate the RS232 serial data stream into an IP packet stream. A second set of POS devices are connected by a databus to Ethernet interface 104 is programmed to translate databus signals into an IP packet stream. Event manager 15 is programmed to receive IP packet streams from Ethernet interface 104 and parse the data for POS events.

For alarm applications, set of I/O closure devices 106 are connected by wired connections to Ethernet interface 104 the Ethernet interface functioning to translate physical closure events from each I/O closure device into an IP packet stream describing the event. Event manager 15 is programmed to receive IP packet streams from Ethernet interface 104 and parse the data for I/O closure events.

Event manager 15 is further programmed to store information about each parsed event in SQL database 21, the information including at least the source of the event, the timestamp of the event, and a priority for the event. Attached to event manager 15 is alarm delivery service 13. Alarm delivery service 13 functions to create alarm events based on event thresholds, associate alarms to actors, and to deliver a communication to an actor upon an associated alarm event. Actors can be services within network video recorder 1. For example, an I/O closure event triggers an alarm and alarm delivery service 13 functions to send a message to a person via email, text, paging, or smart phone push. Alarm delivery service 13 also functions to log all alarms to SQL database 21.

In one embodiment the smart phone push is a simple SMS text message. In other embodiments, smart phone applications are conceived that continuously operate on the smart phone to receive event information in real time over the internet, display the event information and provide user options for response. In other embodiments, a fully functional IP client station is implemented in a smart phone application allowing a user to fully interact with network video recorder and video devices. The HTTP server of the network video recorder is configured to recognize the device type of the IP client station, including smart phone devices and serve web pages suitable for smart phone web browsers and hybrid smart phone applications. Suitable smart phones are at least the iPhone set of devices from Apple Computer, Inc and the Android operating system based devices available from many different hardware vendors, the Android operating system being a product developed by the Open Handset Alliance.

IP client station 2 is programmed to query SQL database 21 and receive responses describing events and alarms as stored in association with encoder box 103 and Ethernet interface 104.

Media recorder 10 functions to select at least one camera from the set of analog cameras through communications with encoder box 103 and stream video from encoder box 103 to recorded video files stored in media database 20. Media recorder 10 also functions to stream video directly from encoder box 103 to the video display monitor of the network video recorder. IP Client station 2 functions to stream video to display directly from encoder box 103 for live video files and via media recorder 10 from recorded video files.

FIG. 12 is a block diagram depicting a virtual video matrix system 200 enabled by the third exemplary embodiment of the carrier board. Virtual video matrix system 200 comprises a video recorder device 201 connected by a local area network to a set of video recorder devices 204. Video recorder device 201 includes a carrier board configured with a high definition video subsystem as described in relation to FIG. 8. The high definition video subsystem is a discoverable network device on the local area network, having an IP address to enable communications to/from any device attached on the local area network. The high definition video subsystem includes HDMI port 206 for exporting HD video signals to a spot monitor 205 capable of displaying high definition video. The HD video signals comprise a set of video streams, each of which are displayed by spot monitor 205. While the preferred embodiment includes a 4×4 matrix display capable of simultaneously displaying 16 video streams, the present invention is not limited by a size or number of displayed video streams.

A virtual video matrix comprises a set of video streams available from all camera devices connected to the set of video recorder devices 204 and video recorder device 201. A manual control 203 is included on first video recorder device 201 for selecting video scenes from the virtual video matrix. Selection of video scenes can also be accomplished by IP client station 202 which is connected to video recorder device 201.

In operation, spot monitor 205 is placed in proximity to video recorder device 201 and connected thereto. Video recorder device 201 and set of video recorder devices 204 are connected to the set of camera devices and further configured to compress and stream a set of compressed video streams from each of the set of camera devices to the high definition video processor subsystem in video recorder device 201. A subset of the compressed video streams is selected by the manual control provided on video recorder device 201. The high definition video subsystem then decompresses the selected compressed video streams and combines the resulting uncompressed video streams into a single composite video stream. The single composite video stream is converted to HDMI format by the high definition video subsystem and put out to the HDMI port where it is transmitted to the spot monitor and displayed.

In operation, video recorder device 201 acts as a master video recorder device. Each video recorder device in the set of video recorder devices 204, acts as a slave device. The master video recorder device receives instructions from the IP client station and transmits those instructions to each slave device. Accordingly, each slave device sends alarms and event information to the IP client station through the master video recorder device, which is configured to consolidate the information stored on the set of video recorder devices 204. In a preferred embodiment, the virtual video matrix system is operated by the master video recorder device.

If an auto IP client is connected to video recorder device 201, the compressed video streams can be selected for display via user interaction on the IP client station. The IP client station is configured to display a representation of the single composite video stream on a computer monitor showing detailed information relating to each compressed video stream.

Referring to FIGS. 10 and 13, in use, the network video recorder receives instructions from the IP client station at step 120, the instructions related to preferences of the user with respect to configuration of the network cameras. For example, camera choices, delay times, and PTZ parameters are selected through a graphic user interface produced by the client software operating on the IP client station.

At step 122, the IP network discovery service running on the network video recorder searches the network for available cameras connected at the RJ45 ports. At step 124, the Ethernet port controller associated to each RJ45 port reports specific connectivity data on a connected camera or other network security device including a fixed Mac-address, if available, which is stored in the SQL database. At step 126, the network video recorder then configures, i.e., programs each of the cameras, according to camera specific data stored in the persistent memory (compact flash memory or mass storage device).

Once configured, step 128 is performed wherein the media recorder sets up streaming protocol channels to the cameras, and the event manager receives event and alarm data from the cameras including video streams and event transactions, according to instructions from the scheduler. At step 130, video streams are stored in the media database and event/alarm transactions are stored in the SQL database via the mass storage device on the SATA port.

IP network discovery and automatic configuration is further explained using the time sequence diagram of FIG. 25. Automatic configuring process 700 involves a network video recorder (NVR) 701, a set of cameras including camera 702, and update server 703. The interaction between NVR 701 and camera 702, and NVR 701 and update server 703 is depicted in a time sequence where time progresses from the top of the diagram to the bottom. At step 704, camera 702 is connected to a LAN Ethernet port of NVR 701. At step 705, the LAN Ethernet port of NVR 701 provides power to camera 702 by sending a power signal to the camera via PoE protocol (see IEEE standards 802.3af and 802.2at). At step 706, camera 702 broadcasts a “hello” message using Bonjour or similar networking protocol to send a set of connectivity data that includes make, model, inherent capabilities, and MAC address to NVR 701. At step 707, NVR 701 provides an IP address to camera 702 via the NVR's DHCP service.

At step 708, NVR 701 determines a set of video parameters for camera 702 based on the set of connectivity data. The set of video parameters includes at least the parameters related to video compression, video frame rate, video quality, video resolution and data transfer rate for the cameras. In this step, NVR 701 searches the SQL database for a match between the set of connectivity data and the set of video parameters. If a match is determined, then process 700 proceeds to step 714. If a match is not determined, then process 700 proceeds to step 709. At step 709, NVR 701 requests the set of video parameters from update server 703. At step 710, update server 703 searches its database for the requested set of video parameters. At step 711, update server 703 retrieves the requested set of video parameters. At step 712, update server 703 sends the set of video parameters to NVR 701. At step 713, NVR 701 saves the set of video parameters into memory.

At step 714, NVR 701 sends the set of video parameters to configure camera 702 with the set of video parameters. At step 715, NVR 701 synchronizes the camera time by providing an NTP service. At step 716, NVR 701 sets up event delivery for camera 702 by communicating NVR's IP address to camera 702 as the destination IP address for camera events. At step 717, NVR 701 sets up motion detection in camera 702 by communicating motion related parameters including at least the motion area and motion detection sensitivity. At step 718, a streaming video session is established by NVR 701 between camera 702 and NVR 701. The streaming video session is preferably set up as an RTSP (real-time streaming protocol) session. At step 719, NVR 701 configures its media recorder to record streaming video. At step 720, camera 702 streams video to NVR 701 via the established streaming video session. The video is streamed across the LAN preferably using one of UDP over IP protocol and TCP over IP protocol. At step 721, NVR 701 receives and records the established streaming video session.

Digital view controls 330 include an adjustable zoom box 309 object that when set displays a zoomed video stream 308 as a single video panel in video view area 305.

Alarm panel GUI 310 is shown in FIG. 16 having a time period control 311, an event type control 313 and a queue size control 315. Alarm panel GUI 310 has a camera control 321 for selecting cameras. Alarm panel GUI 310 includes a set of operating controls 324 to control perform various alarm related functions as will be explained below. Alarms are displayed in rows of alarm panel GUI 310 with columns indicating event type 312, site name 314, camera 316, event time 317, a set of selectors for live video 318, a set of selectors for playback video 319, and a set of delete buttons 320.

In FIG. 17, IP client GUI 300 is configured to operate a multi-search playback window comprising a search window 342 in the tree view area, a camera search dialog 344 in the camera controls area, a set of video panels 307 in the video view area and slider panel 346 in the instrument view area. Slider panel 346 comprises a set of track bars, one track bar for each video panel in the set of video panels, wherein the track bars are displayed on a time scale 347 with a tracking time indicator 343 indicating a point of time in a video stream. A set of slider controls 348 are included in slider panel 346 to control the tracking of video streams.

In FIG. 18, a site administration GUI 350 is shown in another screen shot. Site administration GUI 350 includes a set of dialogs accessible by selectable tabs displayed in the GUI window. The set of dialogs comprise a camera management dialog 352, an NVR management dialog 354, a user management dialog 355, a system preferences dialog 356, a system information dialog 357 and an NVR logs dialog 358. The NVR management dialog 354 is opened and further includes a set of NVR management functions including network configuration dialog 360, datetime dialog 362, service status dialog 364 and a maintenance dialog 365. The maintenance dialog is opened showing software status 367 and an upload tool 368 for uploading IP client software updates from the NVR server to the IP client station. At the bottom of the screen shot is shown a button 370 used to save changes to the NVR server and exit button 372 to exit site administration GUI 350, stopping its execution. All of the dialogs in site administration GUI contain buttons 370 and 372.

Referring to FIGS. 14-18 and 19-24, operation of the IP client application functions will be described.

Beginning with method 500 of FIG. 19, IP client station is started at step 501. At step 502, a user is required to login to the IP client application to access its functions and features. After authentication at step 503, a dialog is presented to the user at step 504 where a NVR server is chosen as a primary NVR server for the IP client station. The NVR server is chosen according to one of steps 507, 508 and 509: at step 507, by selecting a profile from an existing set of profiles; at step 508 by creating a new profile; and, at step 509 by automatically discovering a NVR server attached to the local area network. If a network video recorder is in a remote network a remote IP address is required to discover a NVR server.

A multi-site login feature allows users to access more than one server from the IP client GUI including a primary server and a set of second servers. The primary server is the server with which the user initially logs in. For example, if the user logs into a server with an IP address of 10.100.200.9, then this IP address is referred to as the primary server and can be seen under the “sites” folder in the tree view area. Secondary servers are added as described below.

Creating a profile, at step 508, involves the steps of selecting a profile name, adding a set of sites to the profile, setting an IP address for an NVR server for each site by setting a username, setting a password associated to the username, setting a connection type as either LAN or remote, configuring the HTTP and RTSP ports, editing a text description of the NVR, and saving the profile. Additional sites can be added to the profile at a later time and the profile can be edited with updated information as required.

In the step 509 of discovering a NVR server, IP client application executes a zero configuration protocol to discover a list of available NVR servers with their corresponding IP addresses. A profile is created and edited from the resulting list of discovered NVR servers.

At step 505, a graphical user interface (GUI) similar to that of FIG. 14 is displayed and operated allowing the IP client application to perform a wide range of functions. The name of the user and the IP address of the primary NVR server are displayed in a visible area.

At step 506, a means for executing various functions to manage all attached NVR servers, all cameras in the networks of each attached NVR server, and video recordings stored in the attached NVR servers.

In the preferred embodiment, a menu of icons in a tool bar is provided in the GUI that when selected allows the various functions to be performed. As shown in FIG. 14, the tool bar area operates as follows. Selecting the camera bar icon 383 opens a camera tree view. Selecting the search icon 381 opens a multi-search window as described below. Selecting an alarm icon 384 displays an alarm panel in the instrument panel area. Selecting a layout icon 382 allows a user to set a video viewing format in the view area. Video viewing formats relate to the number of video streams displayed simultaneously as video panels in the view area. For example, a single view displays only one video panel consuming the entire view area; a 4×4 view displays sixteen video panels in the view area. Selecting a fit screen icon 385 adjusts a set of selected video streams to fit the entire video view area leaving the tool bar menu, tree view area, camera control area, instrument panel area, and operating system menus visible. Selecting a full screen icon 386 adjusts a set of selected video streams to fit the entire GUI area leaving the tool bar menu and operating system menus visible. Selecting a monitor screen icon 387 adjusts a set of selected video streams to fit the entire display screen and hiding the tool bar menu and the operating system menus. Selecting a refresh icon 390 refreshes all video streams in the video view area and all information in the tree view area and the instrument panel area. Selecting a mute icon 392 mutes any available audio originating from the set of video streams. Selecting a “close all” icon 389 closes all camera windows leaving only the toolbar menu and the tree view area. Selecting an admin icon 388 displays an administration window wherein a user logs on as an administrator.

FIG. 20 shows a method 510 to manage a set of sites, a set of cameras attached to the network at each site, a set of views and a set of camera tours. At step 512, selecting a camera bar icon in the tool bar area opens a camera tree view. At step 514, a camera tree is displayed in the tree view area including a hierarchical tree level view of a list of sites which is a list of NVR servers, a list of cameras attached to each NVR server, a set of pre-defined camera views and a set of pre-defined camera tours.

The camera tree view functions as follows. Entities in the camera tree view are normally opened by “left-selecting” for display by left-clicking with a mouse pointer on the entity's icon or by clicking an adjacent “+” icon. Properties of the entity are normally opened for display and editing by “right-selecting” which is right-clicking with a mouse on the entity's icon. The cameras in the network display in a tree structure with associated icons which indicate if a camera is online, is not online, is a PTZ capable camera, and is not a PTZ capable camera.

At step 516, a sites dialog is opened to manage sites by right-selecting the “sites” folder. Multiple sites can be added to a profile by choosing to add a new site in the sites dialog. If the user chooses to add a new site, the GUI displays a new login form wherein the user can manually enter the site information or use server discovery. Using the camera tree view, the user can connect to “N” number of secondary NVR servers. For example, if the user logs into the NVR server with the IP address of 10.100.200.9 (primary server) with a profile, then adds an additional secondary NVR server with an IP address of 204.246.206.103, then the newly added secondary site appears under the “sites” folder with its corresponding IP address by default. Sites can be renamed to make the “site” folder displays more useful. Cameras in a given site can be viewed by right-selecting a site folder.

Further to step 516, the “sites” dialog allows for disconnecting or connecting a site from communications with the IP client station. By default, a site folder icon and all of its camera icons appear in red in the camera tree when it is disconnected. The “sites” dialog also allows for deletion of the site. In the preferred embodiment, the primary site cannot be deleted.

The “sites” dialog allows for a site administrator application to execute. Alternatively, the “admin” icon on the toolbar menu can be selected to execute the site administrator. The site administrator application displays and operates an Administration page for a selected site as described further below.

A subset of layouts are predefined and stored within a view group's folder which is displayed in the camera tree. At step 520, views are managed by right-selecting the view group's icon to open a views dialog. At step 524, a set of view groups are created within a folder according to views dialog. A view group is a named folder used to hold a description and a set of view layouts. At step 525 the set of view layouts are created in the views dialog from a selected set of cameras. A view layout has a name, a description, a set of assigned video streams. Once created, existing view groups can be edited and deleted. For example, a view group for a warehouse contains a single 2×2 view layout simultaneously displaying four video streams from an outside door, a first set of inventory, a second set of inventory and an office.

Specifications for a set of camera tours are predefined and stored within a camera tours folder and the set of camera tours are displayed in the camera tree by left-selecting the camera tours folder. A camera tour displays a set of live video streams from a set of cameras in the set of video panels. A camera tour skips any offline cameras while displaying.

At step 522, a camera tour is added by right-selecting the camera tours folder. At step 527, the set of cameras is selected for a given camera tour. At step 528, the order of display is specified for the given camera tour. At step 528, a uniform dwell time is specified between each video stream display for the given camera tour. A camera tour can also be deleted or edited wherein individual cameras can be removed or added to an existing camera tour.

From the camera tree view, a live video stream is displayed in a video panel by dragging and dropping the camera name from the camera tree on the left into the video view area, double-clicking on the desired camera name, or right-selecting the camera name then choosing “View Camera.” A live video stream may be deleted by clicking an “unpin” icon indicated near the live video display.

In the preferred embodiment of the IP client GUI, the live video window initializes after login by default showing the camera tree in the tree view area, a set of video panels in the video view area, PTZ and zoom controls in the camera controls area, and an alarm panel in the instrumental panel area.

In FIG. 21, step 531, the camera controls are enabled by selecting a camera by clicking an icon in the camera tree view or by selecting a video panel in the video view area.

At step 532, the IP client GUI determines if the selected camera is PTZ enabled. If the selected camera is PTZ enabled then the camera controls operate in mechanical control mode 534. If the selected camera is not PTZ enabled then the camera controls operate in the digital zoom mode 536.

Digital zoom mode 536 is also enabled by selecting a digital control button. During live or playback video streaming, zoom is determined in step 538, by sizing an adjustable area defined by a digital zoom box positioned over a video panel as displayed in the camera control area. The picture corresponding to the selected digital zoom box is enlarged and displayed in the camera's live or playback view panel in the video view area.

Mechanical control mode 534 is also enabled by selecting a mechanical control button in the camera control area. In mechanical control mode 534, a set of PTZ controls are further enabled. For live video streams, the set of PTZ control interacts with a selected PTZ-enabled camera. The PTZ-enabled camera is selected by clicking on a live video panel in the video view area. The set of PTZ controls allows for controlling zoom 540, controlling pan 542, controlling tilt 544, controlling iris 545 and controlling focus 546. At step 548, PTZ speed of movement is set during preset PTZ tours. Furthermore, the set of PTZ controls include the use of preset camera positions, tours and settings. At step 550, preset positions are set and stored using the PTZ controls. When a preset position is selected, the PTZ-enabled camera automatically moves to the corresponding preset position. At step 552, an external joystick is attached to the IP client station, and at step 554, the external joystick control operates the PTZ control functions.

Method 560 of FIG. 22 explains the function of an alarm panel (see FIG. 16 also). During live video streaming, at step 562, an alarm panel displays in the instrument panel area. The alarm panel can also be used as a shortcut for viewing playback video related to an alarm. The alarm panel is also turned on or off by clicking the alarm icon in the toolbar menu area.

Alarms are set up by entering and selecting information into the alarm panel for a given alarm. Fields of information and information selectors are available in the alarm panel. At step 564, the period of time for which alarms are displayed in the alarm panel is entered. At step 566, the type of events for receiving alarm notifications is selected from a list. At step 568 the maximum number of alarms displayed in the alarm panel is entered. At step 570, a camera selector dialog is opened to select cameras for viewing in the alarm panel. At step 572, alarm tracking is started. At step 574 alarm tracking is stopped. At step 576 a “playback in same window” selector is selected to playback recorded video within the video panel corresponding to the camera's live video stream.

Search criterion are selected from the group of cameras, start time, end time, audio events, motion detection events, contact closure events, scheduled events and a combination thereof.

At step 588, selecting a search control activates a search based on the entered criteria by transmitting the search criterion and the selection of cameras to one or more NVR servers. The NVR servers perform the search functions to provide search results in the form of recorded video streams. At step 590, the search results are received by the IP client GUI and displayed according to the video panel layout format.

At step 592, a slider panel with a set of track bars displays the time between the start time and end time in the search criteria. At step 594, events returned from the search are displayed in an event window. Events in the event window are selected for viewing in the camera's assigned video panel according to the selected video panel layout format. Alternatively, selecting a camera's assigned view panel brings up all returned events for that camera in the event window.

At step 594, a history window is selected from the search window which displays camera logs as stored in the NVR server corresponding to the cameras. Selecting an entry in the history windows causes the corresponding video stream to appear in the corresponding camera's assigned video panel. The history window displays event history according to a searched start time and end time. After selecting a particular item from the list, the selected camera track and time period display in the slider panel.

At step 597, playback controls provided in the slider panel are manipulated to manage the video playback. The set of vertical tracking bars in the slider panel each move to a designated time as returned by the search while the corresponding playback video streams display in a video panel. A set of playback controls are included in the slider panel allowing individual control of each video stream selected in the search. During playback of multiple video streams, a slider control can be used to display video at a specific time by moving the slider control horizontally along a track. The set of playback controls also include play, pause, stop, step backward, rewind, step forward, fast forward, jog speed and export. According to step 599, a synchronization control allows the recorded video streams from multiple cameras to be played back synchronously or asynchronously, as selected.

At step 598, the export playback control causes recorded videos to be exported to local non-transitory storage media according to a set of menu driven options which include writing the video streams to files on a CD/DVD.

Each track bar is displayed in coded colors to distinguish playback features. Video panel layout options are also accessible via the slider panel during playback. Also, while in playback, the camera control area allows for digital zooming of recorded video streams.

This registration process allows the system to monitor specific instances of hardware and to understand their relationship to each other.

At step 3414, Monitoring Sink API 3408 sends instructions to the Monitoring service relating to the device component hierarchy related to the device tree. The device tree lists all the devices in a parent-child relationship allowing the creation of Device Providers that will monitor the health of each device.

At step 3416, Monitoring Service 3404 creates Device Providers for each hardware component and begins polling their health and operating conditions. Sensor and device properties are captured and reported on a timed basis.

At step 3418, sensor data is passed back to Monitoring Sink API 3408, which parses the data and updates specific databases for a Management API, such as Management API 3318 of FIG. 33, to poll.

At step 3420, a “ping or heartbeat” message is sent from Monitoring Service 3404 to Monitoring Sink API 3408 to ensure one or more devices of the system are connected to the network and operational.

Referring to FIG. 35, system 3500 includes network video recorder (“NVR”) 3501 having a processor and a memory. Binding application 3502 is saved in the memory and executed by the processor. Binding application 3502 communicates with switch management serial interface 3503 to run MAC address discovery and binding process 3504 and camera identity discovery process 3505 on set of Ethernet ports 3506, which are connected to a set of client devices 3507. Binding application 3502 is further connected to web user interface 3509 through network 3508.

In one embodiment, each of set of client devices 3507 is an IP camera. Any type of IP connected device may be employed.

In a preferred embodiment, network 3508 is a wide area network such as the Internet, but can encompass other wide area networks and intranet systems, including cellular networks.

Referring to FIG. 36, method 3600 for binding an Ethernet port to a client device is described. At step 3601, the NVR polls each client device of a set of client devices for its MAC address and a set of signature identifiers. In a preferred embodiment, the set of signature identifiers includes factory programmed identity information, including manufacturer, model no., and serial no., and measurements including power consumption. Other types of identifying data may be employed.

At step 3602, the NVR receives the set of data including the MAC address and the set of signature identifiers. At step 3603, the set of data is saved into memory. At step 3604, the NVR binds each client device to a respective Ethernet port using its respective set of data. In this step, the NVR limits communications on the respective Ethernet port to the connected client device according to the set of data.

Referring to FIG. 37, method 3700 is a process to bind a MAC address of camera 3708 to a port of switch 3706 of network video recorder system 3704. The binding process can be handled entirely by network video recorder system 3704. Optionally, network video recorder system 3704 can receive instructions from user device 3702 through cloud server 3703 to bind the MAC address of camera 3708 to the port of switch 3706.

At step 3711, camera 3708 sends its MAC address to switch 3706 of network video recorder system 3704. Camera 3708 sends its MAC address after being connected to the port of switch 3706.

At step 3712, switch 3706 generates a table of MAC addresses. The table identifies which MAC addresses have been used on each of the ports of switch 3706, an example of which is shown below.

Port MAC Address 00 Null 01 Null 02 Null 03 Null 04 12:34:56:78:9A:B9 05 12:34:56:78:9A:BA 06 12:34:56:78:9A:BB 07 12:34:56:78:9A:BC Each row includes a field for a port number and a field for a MAC address. Ports 00 through 03 are not being used and ports 04 through 07 are connected to devices that are respectively using MAC addresses 12:34:56:78:9A:B9, 12:34:56:78:9A:BA, 12:34:56:78:9A:BB, and 12:34:56:78:9A:BC.

At optional step 3713, a button on network video recorder system 3704 is pushed to start the process of binding the MAC addresses to the ports. When the button is pushed, the process can proceed to automatically make all of the port bindings using the current MAC table of switch 3706. Without pressing the button, network video recorder system 3704 identifies new MAC addresses and requests instructions for binding the new MAC addresses.

At step 3714, processor 3705 sends a request to switch 3706 for the MAC table.

At step 3715, switch 3706 sends the MAC table to processor 3705.

At optional step 3716, processor 3705 identifies a new MAC address in the MAC table that has not been bound to a port.

At optional step 3717, processor 3705 displays the MAC address table and the unbound MAC address to a display connected directly to network video recorder system 3704.

At step 3718, processor 3705 sends the MAC table to cloud server 3703.

At optional step 3719, cloud server 3703 generates an alert for the MAC address that has not been bound to the port.

At optional step 3720, cloud server 3703 sends the alert to user device 3702.

The alert is sent as an SMS message, the text of which includes the port number, the MAC address, and a description that states that there is no binding between the port and the MAC address.

-   -   “2017-01-06-16:38 Port-06 MAC-12:34:56:78:9A:BB no binding         between MAC and port!”

At optional step 3721, user device 3702 displays the alert with the unbound MAC address.

At optional step 3722, user device 3702 generates a message for accepting the MAC address and creating a binding between the MAC address and the port. The message is generated as an SMS message that includes a command “BIND” and identifies the port and the MAC address to bind, an example of which is shown below.

-   -   “BIND Port-06 to MAC-12:34:56:78:9A:BB”

At optional step 3723, the acceptance message that includes the binding command is sent from user device 3702 and is received by cloud server 3703.

At optional step 3724, cloud server 3703 generates acceptance instructions. The acceptance instructions are generated by converting the text from the acceptance message to API calls or binary instructions for network video recorder system 3704.

At optional step 3725, cloud server 3703 sends the acceptance instructions to processor 3705 of network video recorder system 3704.

At step 3726, processor 3705 generates binding instructions. If a button push was received at step 3713, then processor 3705 generates binding commands for switch 3706 that will create a binding between any previously unbound MAC address and port number. If the button push was not received and acceptance instructions were received from cloud server 3703, then processor 3705 generates the binding commands from the acceptance instructions received from cloud server 3703.

At step 3727, the binding instructions are sent from processor 3705 to switch 3706.

At step 3728, switch 3706 stores the bindings.

At step 3729, after the bindings are stored on switch 3706, camera 3708 begins sending video information as an RTSP stream and the packets of the stream will not be rejected by network video recorder system 3704.

Referring to FIG. 38, method 3800 handles packets that use an incorrect MAC address and passes alerts to user device 3802. User device 3802 accesses information and video related to network video recorder system 3804 and camera 3808 through cloud server 3803 and can be embodied as a portable handheld wireless communication device, such as a smartphone. Cloud server 3803 provides access to one or more network video recorder systems 3804. Network video recorder system 3804 includes processor 3805 and switch 3806 and provides access to one or more cameras 3808. Camera 3808 is an IP camera that provides a live video stream.

At step 3811, camera 3808 sends a packet with video information that is received by switch 3806. The packet includes the MAC address of camera 3808. The packet is sent after camera 3808 has been connected to a port in switch 3806 of network video recorder system 3804 and the MAC address has not been bound to the port of switch 3806.

At step 3812, an event is logged. The event identifies that a packet was received on a port of switch 3806 that includes the MAC address from camera 3808, which has not been bound to the port of switch 3806.

At step 3813, the packet from camera 3808 is rejected by switch 3806. The packet is rejected because the MAC address in the packet has not been bound to the port in switch 3806 that received the packet, which is referred to as an incorrect MAC event with the MAC addresses being referred to as incorrect MAC addresses.

At step 3814, processor 3805 sends a request to switch 3806 for a list incorrect MAC events. The request includes a date threshold, a number threshold, and a sort identifier. The date threshold identifies a date and time, where events that were received before the date threshold are ignored. The number threshold is a value that identifies the maximum number of incorrect MAC addresses to include in the list. The sort identifier indicates if the list of MAC addresses will be sorted in forward or reverse order and indicates if the list of MAC addresses will be sorted by date and time of event or by MAC address value.

At step 3815, switch 3806 generates a list of events that includes an incorrect MAC address. Switch 3806 searches its event log to identify the events where switch 3806 rejected a packet because the packet included an incorrect MAC address that was not assigned or bound to the port that received the rejected packet. The list of events is filtered in accordance with the date threshold, then sorted in accordance with the sort identifier, and then filtered in accordance with the number threshold.

At step 3816, switch 3806 sends the list of incorrect MAC address events to processor 3805.

At optional step 3817, processor 3805 displays the list of incorrect MAC address events on a display connected directly to network video recorder system 3804.

At step 3818, processor 3805 increases the poll rate for a pre-determined amount of time, such as twenty four hours. The poll rate identifies how often processor 3805 polls switch 3806 for rejected MAC events.

At step 3819, processor 3805 of network video recorder system 3804 sends the list of incorrect MAC address events to cloud server 3803.

At step 3820, cloud server 3803 generates an alert based on the list of incorrect MAC address events. Each alert includes the time, date, port number, and MAC address for one of the incorrect MAC address events.

At step 3821, cloud server 3803 checks for predefined instructions. The predefined instructions can be used to handle the incorrect MAC address events without the need for user interaction with the system. In one embodiment, the predefined instructions cause the system to shut down any ports associated with an incorrect MAC address event.

At step 3822, cloud server 3803 generates an SMS message from an incorrect MAC address event. The SMS message is an alert that includes the date, time, port, MAC address, alert, and description of the event in a human readable format. Below is an example of the text in an SMS message generated by cloud server 3803.

-   -   “2017-01-06-16:58 Port-07 MAC-12:34:56:78:9A:BC PACKET         REJECTED-MAC not bound to port”         Alternative embodiments may use different message protocols.

Referring to FIG. 38B, at step 3823, the SMS alert is sent from cloud server 3803 to user device 3802.

At step 3824, user device 3802 displays the alert on a user interface of user device 3802. The SMS alert is displayed in a messaging program running on user device 3802.

At step 3825, user device 3802 generates an SMS text with instructions. The instructions in the SMS are human readable and identify an action to be taken by the system. Below is an example of the message text of an SMS with an instruction that will cause the system to turn off the power to port 07.

-   -   “Port-07TURN POWER OFF”

At step 3826, the SMS with instructions is sent from user device 3802 to cloud server 3803.

At step 3827, cloud server 3803 stores and processes the instructions from the SMS received from user device 3802. Cloud server 3803 converts the instructions from a text format into API calls or binary instructions that can be used by network video recorder system 3804.

At step 3828, the instructions are sent from cloud server 3803 and received by processor 3805 of network video recorder system 3804.

At step 3829, processor 3805 of network video recorder system 3804 records the receipt of the instructions into a log file.

At step 3830, processor 3805 decreases the poll rate. The poll rate is decreased back to the level it was at before the poll rate was increased at step 3818.

At step 3831, the instructions are sent to switch 3806 from processor 3805.

At step 3832, switch 3805 executes the instructions and turns off communication and/or power to the port that received the packet that was rejected. Turning off all communication with the port will throw away any packets received from that port so that there is no communication with the port of either sending or receiving packets. Turning off all communication protects the system from being compromised by a laptop or other unauthorized device being plugged into the port instead of an authorized camera that has been paired with the port.

At optional step 3833, camera 3808 shuts down after the power is removed from the port.

At step 3834, switch 3806 sends an acknowledgment to processor 3805 that indicates that the communication, power, or both, to the port that received the rejected packet with the incorrect MAC address has been turned off.

At step 3835, processor 3805 processes the acknowledgment and updates the status of the port. The status of the port is updated to identify that there is no communication with the port, that no power is being provided to the port, or both.

At optional step 3836, processor 3805 displays the power status of the port.

At step 3837, processor 3805 sends the status of the port to cloud server 3803.

At step 3838, cloud server 3803 generates an SMS message that include the power status of the port. Below is an example of text of the SMS message to indicate that the power has been turned off to the port.

-   -   “2017-01-06-17:18 Port-07 POWER OFF”

At step 3839, the SMS message with the status is sent from cloud server 3803 to user device 3802.

At step 3840, user device 3802 displays the message that the power to the port has been turned off after receiving the SMS from cloud server 3803.

Referring to FIGS. 39A, 39B, and 39C network video recorder 3900 includes heatsink 3902, and a plurality of ports 3904. FIG. 39B shows network video recorder 3900 after it has been rotated 180 degrees about the y-axis and with the bottom cover removed. Removing the bottom cover exposes printed circuit board (PCB) 3906 that includes the CPU board, the switch board, memory, and persistent storage.

Heaters 3910 and 3912 are positioned adjacent the CPU board. Heaters 3914, 3916, 3918, and 3920 are positioned adjacent critical circuits on the PCB. Thermally conductive paste 3924, 3926, 3928, 3930, 3932, and 3934 is typically applied between the circuits and the aluminum heatsink to facilitate heat transfer.

A first group of heaters comprising heaters 3910 and 3912 are connected to header 3934, a second group of heaters comprising heaters 3914 and 3916 are connected to header 3936, and a third group of heaters comprising heaters 3918 and 3920 are connected to header 3938. Headers 3934, 3936, and 3938 connect to the CPU board of PCB 3906 so that the CPU board can control heaters 3910 through 3920. Each of the first, second, and third groups of heaters can be controlled independently. Heaters 3910 through 3912 are attached directly to aluminum heatsink 3908 so that heat can transfer through aluminum heatsink 3908 to the chips connected to aluminum heatsink 3908 through thermally conductive paste 3922 through 3934.

Referring to FIGS. 40A and 40B, a schematic of network video recorder system 4000 is shown that includes computer system 4001 and switch system 4051. Computer system 4001 and switch system 4051 share a single printed circuit board. Alternative embodiments can have computer system 4001 and switch system 4051 as separate printed circuit boards.

Processor 4002 is connected to high definition multimedia interface (HDMI) port 4003, peripheral component interconnect express (PCIe) port 4004, memory 4005, and platform controller hub 4006. In a preferred embodiment, processor 4002 is an i5-4400E manufactured by Intel Corporation.

Platform controller hub 4006 provides access to lower bandwidth devices. In a preferred embodiment, platform controller hub 4006 is a QM87 manufactured by Intel Corporation. Platform controller hub 4006 is connected through video graphics array (VGA) bus 4007 to VGA port 4008, through serial peripheral interface (SPI) bus 4009 to SPI flash memory 4010, through universal serial bus (USB) 4011 to USB port 4012, through serial AT adapter (SATA) bus 4013 to SATA port 4014, through low pin count (LPC) bus 4015 to super I/O controller 4016, through PCIe bus 4017 to Ethernet controller 4018, through PCIe bus 4019 to Ethernet controller 4020, through USB 4021 to USB-to-I2C converter circuit 4022, and through PCIe bus 4023 to Ethernet controller 4024.

Super I/O controller 4016 is connected to heater controller 4026, which is connected to heaters 4027, and super I/O controller 4016 is connected to temperature sensor 4028. Heaters 4027 are placed substantially near or adjacent to chips in network video recorder system 4000. Processor 4002 controls heaters 4027 so that network video recorder system 4000 can safely operate in temperatures as low as −40 degrees Celsius, which is below the normal operating range of the individual chips used in network video recorder system 4000. Super I/O controller 4016 gets the temperature of network video recorder system 4000 from temperature sensor 4028 and controls heaters 4027 based on the measured temperature.

Ethernet controller 4018 is connected to fiber port 4029 and Ethernet controller 4020 is connected to RJ45 port 4030 that includes a transformer. Fiber port 4029 and RJ45 port 4030 are uplink ports that can be connected through the internet to a cloud server. Ethernet controller 4024 is connected to transformer 4025 and provides an Ethernet connection between processor 4002 and switch controller 4052.

USB-to-I2C converter circuit 4022 provides for the connection to power over Ethernet (PoE) controller 4075 and to switch controller 4052. Commands to control power over Ethernet controller 4075 and to switch controller 4052 are sent from processor 4002 using the inter-integrated circuit (I2C) interface.

Local power converter 4031 provides power to the chips and components on computer system 4001. Local power converter 4031 converts the 12 Volt direct current (DC) power from converter 4087 to 3.3 Volt and 5 Volt power.

Switch controller 4052 on switch system 4051 is controlled by processor 4002 through an I2C bus. In a preferred embodiment, switch controller 4052 is a DX981133 manufactured by Marvell Semiconductor. Switch controller 4052 is connected through SPI bus 4053 to first memory 4054, through DDR2 bus 4055 to second memory 4056, through source synchronous serial media independent interface (SSSMII) bus 4057 to eight (8) port Ethernet transceiver 4058, through SSSMII bus 4059 to eight (8) port Ethernet transceiver 4060, through SSSMII bus 4061 to eight (8) port Ethernet transceiver 4062, and through serial gigabit media independent interface (SGMII) bus 4063 to dual port Ethernet transceiver 4064.

A first port of Ethernet transceiver 4064 is connected to transformer 4073 and connects to uplink 4074 between switch controller 4052 and processor 4002. A second port of Ethernet transceiver 4064 provides the uplink connection between switch controller 4052 and an external network, such as the internet. The second port of Ethernet transceiver 4064 connects to fiber port 4071 and RJ45 port 4072. One of fiber port 4071 and RJ45 port 4072 is used to connect switch controller 4052 to the external network.

Power over Ethernet controller 4075 is controlled through an I2C bus by processor 4002. Power over Ethernet controller 4075 connects through SPI buses 4076, 4077, and 4078 to isolator 4079.

Referring to FIG. 41, method 4100 is the low temperature boot sequence for a network video recorder system. The network video recorder system includes one or more heaters that allow the network video recorder system to operate at temperatures down to −40 degrees Celsius.

At step 4102, power is turned on to the network video recorder system.

At step 4104, a super I/O chip in the network video recorder system boots up prior to the other systems and pulls down the reset line to the major chips inside the network video recorder system, such as the processor and switch controller. Pulling down the reset line prevents the other chips from performing their respective boot sequences.

At step 4106, the super I/O chip measures the temperature of the network video recorder system. The temperature is measured with a sensor placed inside the network video recorder system.

At step 4108, the super I/O chip determines if the temperature is less than a predetermined low temperature threshold. In a preferred embodiment, the low temperature threshold is −10 degrees Celsius. If the temperature is not less than the low temperature threshold, then the process proceeds to step 4110. If the temperature is less than the low temperature threshold, then the process proceeds to step 4116.

At step 4110, the temperature is not less than the low temperature threshold and the super I/O controller releases the reset lines of the other major chips in the network video recorder.

At step 4112, the system boot sequence starts after the reset lines have been released by the super I/O controller.

At step 4114, method 4100 is completed successfully and the system has booted.

At step 4116, the temperature is less than the low temperature threshold and the super I/O controller turns on one or more heaters in the network video recorder. After turning on the heaters, method 4100 proceeds to step 4118.

At step 4118, the super I/O controller measures the temperature of the network video recorder after the heaters have been turned on.

At step 4120, the super I/O controller determines if the temperature is less than the low temperature threshold. If the temperature is not less than the low temperature threshold, then the process proceeds to step 4110. If the temperature is less than the low temperature threshold, then the process proceeds to step 4122. Alternative embodiments may use different low temperature thresholds for steps 4108 and 4120.

At step 4122, the super I/O controller determines if the heaters have been operating for less than a predetermined time threshold. In a preferred embodiment, the predetermined time threshold is 18 minutes. If the heaters have been operating for less than the time threshold, then the process proceeds to step 4124 to create part of a loop that allows the system to heat up above the low temperature threshold for less than a time threshold amount of time, e.g., for less than 18 minutes, before proceeding to end the boot process. If the heaters have not been operating for less than the predetermined time threshold, then the process proceeds to step 4126.

At step 4124, the super I/O controller determines if a hardware interrupt is present. The hardware interrupt is generated by a hardware safety circuit when the temperature is greater than a predetermined high temperature threshold. In a preferred embodiment, the predetermined high temperature threshold is 60 degrees Celsius. If the hardware interrupt is not present, then the temperature is not greater than the high temperature threshold and the process proceeds back to step 4118 to form a loop that prevents the heaters from operating when the temperature of the network video recorder is greater than the high temperature threshold. If the hardware interrupt is present, the temperature is greater than the high temperature threshold and the process proceeds to step 4126.

At step 4126, the temperature of the network video recorder is greater than the high temperature threshold or the time threshold has been met and the power to the heaters is removed.

At step 4128, the super I/O controller continues to hold down the reset line of the other major chips of the network video recorder to prevent the network video recorder from booting.

At step 4130, method 4100 is completed without the network video recorder booting and is identified as a boot failure.
